    "    This ontology extracts information about NeXus classes and fields from\n",
    "    NeXus nxdl definition files on the NeXus GitHub site.\n",
    "    See 'seeAlso' for links to the NeXus project, including licencing information.\n",
    "    This project was undertaken under ExPaNDS WP3.2 (https://expands.eu/)\n",
    "    \n",
    "    Purpose\n",
    "    The ontology is designed to fulfil several purposes. First, it creates unique identifiers\n",
    "    for each of the NeXus fields which would normally exist only within the namespaces of the\n",
    "    defining NeXus classes. This is the primary goal and provides PIDs for annotation and tagging.\n",
    "    The second purpose is to allow, via separate ontologies, NeXus fields and classes to be mapped\n",
    "    onto equivalent or related terms defined elsewhere.\n",
    "    Finally, we hope that this ontology, when used with a tool such as Protege, will provide a\n",
    "    useful 'NeXus Explorer' tool to gain a quick overview of NeXus with links to official NeXus \n",
    "    documentation.\n",
    "    \n",
    "    Design Philosophy\n",
    "    The terms in the ontology are extracted almost entirely from NeXus nxdl definition file and converted to\n",
    "    an OWL ontology using the owlready2 python module (https://pypi.org/project/Owlready2/)\n",
    "    NeXus classes - Base Classes and Application Definitions - are expressed as OWL classes.\n",
    "    NeXus fields, which contain the NeXus metadata, are expressed as Owl data properties.\n",
    "    While NeXus provides a subclassing method ('extends') for NeXus classes, this is not currently reflected\n",
    "    in the corresponding OWL classes.\n",
    "    One can think of the main purpose of the ontology as being to 'flatten' the NeXus fields into a single\n",
    "    namespace, rather than existing in the multiple namespaces of the NeXus classes. This requires longer and\n",
    "    more explicit names for the NeXus fields, which are created by prepending the NeXus base class name to the\n",
    "    NeXus field name. It is very important to note that a NeXus application definition can extend a base class\n",
    "    adding new fields, and that it is understood (see NeXus documentation) that the new fields then reserve names\n",
    "    within the class dictionary in order to avoid later duplication. These new fields are therefore shown as data\n",
    "    properties of the NeXus Base Classes, even though they are defined outside the original class definition.\n",
    "    \n",
    "    NeXus classes are reviewed periodically by the NeXus NIAC. It is anticipated that this ontology can be updated \n",
    "    quickly and automatically to reflect the updated definitions.\n",
    "    \n",
    "    Caveats\n",
    "    Some NeXus classes (e.g. NXtransformations) are related specifically to the class that they are contained in.\n",
    "    This relationship is not preserves.\n",
    "    NeXus allows multiple instances of metadata fields within a dataset. Relating multiple field values to a\n",
    "    single identifier will require a selection algorithm.\n",
    "    \n",
